Patent DE-4012456-A1 (DE)
Inventor: KOEBERLE BERND DIPL ING
IPC: A61B3/08
Filed: 1990-04-19
Abstract: A pattern made up of two partial images in complementary colours (r, g) is generated on a colour television screen. The examinee's test spectacles (15) are fitted with a filter (RF) for one complementary colour on one eye (LA) and a filter (GF) for the other complementary colour on the other eye (RA). Each eye sees the image content to which its filter is opaque as black. Thus both eyes can be tested separately or at the same time with different image contents without the need for blacking out. The examinee sees the test symbols in dark colours against a light background.

Title: Office chair with adjustable back rest - which is locked by spring-loaded friction discs and can be released by lever
Inventor: BEER HERBERT
IPC: A47C1/027
Filed: 1990-05-02
Abstract: The revolving office chair is provided with means to adjust the angle of inclination of the back rest relative to the seat.

Patent DE-4026957-A1 (DE)
IPC: B01F25/74
Filed: 1990-08-25
Abstract: The invention relates to a feed apparatus for the material to be fed to an extruder 14. Apart from a main component, the extruder 14 is fed at least one secondary component, which is to be mixed with the main component and the material throughput of which is set as a function of the consumption of the extruder 14, determined on the basis of the material throughput of the main component. The feeding of the main component takes place via a central shaft 6 into an inlet nozzle 10, into which the discharged material stream is directed with a radial flow component by means of a directing element 8. This material stream is crossed by the material stream of the secondary component, introduced above the outlet 7 of the central shaft 6 into the inlet nozzle with a downwardly directed flow component. The secondary component is incorporated in the material stream of the main component without any back pressure, so that no back pressure of the secondary components occurs. As a result, the material throughput of the main component is reduced to correspond to the material throughput of the secondary components.
